Since 1980, just 16 Division I-A teams have gone through the regular season unbeaten and untied. Of those, nine have lost subsequent bowl games and one was tied.

In other words, it's not easy going undefeated.The WAC's Wyoming sports the best record in college football with a 7-0 record and is one of only six unbeaten-untied teams left, just past the halfway point of the season. The others are Nebraska 6-0, Virginia 6-0, Toledo 6-0, Georgia Tech 5-0 and Houston 5-0.

Looking at the remaining games for each team, the latter three seem to be the most likely to lose.

Toledo may lose this week at Central Michigan (5-1) and also plays Navy Nov. 10.

Georgia Tech must play at Virginia Nov. 3 and has an always-dangerous season finale at Georgia Dec. 1.

Houston has three tough SWC games against TCU, Texas and Arkansas.

Nebraska has at least two tough games left, at home against Colorado Nov. 3 and at Oklahoma Nov. 23.

That leaves Virginia and Wyoming. The Cavaliers have that game with Georgia Tech Nov. 3 and otherwise have pretty clear sailing, although the Nov. 24 season-ender at Virginia Tech (close loser at Florida State, winner over West Virginia) may be a test.

Wyoming of course has to play BYU at home Nov. 10, but may have just as diffcult a time getting past rival Colorado State the week before in Fort Collins.

The Cowboys have gone through a regular season unbeaten three times previously, in 1967, 1956 and 1950.LONG CONTRACT: There've been differing rumors about the origin of Saturday's Weber State-Wyoming game. No, it wasn't put together earlier this year when Kansas State pulled out of its game with the Cowboys. And no, it wasn't put together by good buddies Mike Price and Dennis Erickson a few years ago one night after they'd had a few too many.

According to Wyoming and Weber officials, the origin of the game goes back beyond 1986 when Erickson coached at Wyoming and Price was at Weber. A contract was signed in the summer of 1985, arranged between Gary Cunningham (current Fresno State AD) and former Weber AD Gary Crompton.MORE WYO: Despite sporting the best record in the nation, Wyoming won't have a sellout for this week's game with with Wildcats. In fact the 33,500-seat stadium may not even be half full.

According to Wyoming sports information director Kevin McKinney, a crowd of around 15,000 is expected this week. "It's not just because of Weber," said McKinney. "We have seven home games this year (more than ever) and people have to pick and choose which games they go to."HARD-LUCK LOBOS: Last week's outcome of the Wyoming-New Mexico game, a 25-22 Cowboy win, was typical of results in the two programs since 1987 when Paul Roach and Mike Sheppard took over the at the two schools.

Roach is 33-11 with a program that was solid when he got there, while Sheppard is 6-36 with a program that was in shambles when he arrived. The biggest difference between the two is how they've fared in close games.

In games decided by a touchdown or less, Sheppard is 2-12. On the other hand, Roach is 11-4 in such games. Reverse the close-game records for each and Sheppard would be a more respectable 16-26, while Roach would be a mediocre 26-18.SATURDAY'S PICKS - Air Force and San Diego State join BYU on the sidelines this week, while Wyoming and Hawaii step outside the league for games.

UTEP (3-4, 1-3) at Utah (2-4, 0-3), Noon - The Miners are coming off a big win over Hawaii. But this might be the Utes' last chance for a victory in 1990 . . . Utah 24-16.

New Mexico (2-5, 1-1) at Colorado State (4-3, 3-1), Noon - Both teams suffered their first WAC losses last week. Watch for the Rams to bounce back stronger . . . CSU 35-24.
